RooArgSet Class Reference

RooArgSet is a container object that can hold multiple RooAbsArg objects.

The container has set semantics which means that:

  • Every object it contains must have a unique name returned by GetName().
  • Contained objects are not ordered, although the set can be traversed using an iterator returned by createIterator(). The iterator does not necessarily follow the object insertion order.
  • Objects can be retrieved by name only, and not by index.

Ownership of contents

Unowned objects are inserted with the add() method. Owned objects are added with addOwned() or addClone(). A RooArgSet either owns all of it contents, or none, which is determined by the first add call. Once an ownership status is selected, inappropriate add calls will return error status. Clearing the list via removeAll() resets the ownership status. Arguments supplied in the constructor are always added as unowned elements.

Read the contents of the argset in ASCII form from given stream.

The stream is read to end-of-file and each line is assumed to be of the form

<argName> = <argValue>

Lines starting with argNames not matching any element in the list will be ignored with a warning message. In addition limited C++ style preprocessing and flow control is provided. The following constructions are recognized:

include "include.file"

Include given file, recursive inclusion OK

if (<boolean_expression>)
<name> = <value>
....
else if (<boolean_expression>)
....
else
....
endif

All expressions are evaluated by RooFormula, and may involve any of the sets variables.

echo <Message>

Print console message while reading from stream

abort

Force termination of read sequence with error status

The value of each argument is read by the arguments readFromStream function.

Write the contents of the argset in ASCII form to given stream.

A line is written for each element contained in the form <argName> = <argValue>

The <argValue> part of each element is written by the arguments' writeToStream() function.

Parameters
osThe stream to write to
compactWrite only the bare values, separated by ' '. Doing this, the stream cannot be read back into a RooArgSet, but only into a RooArgList, because the key names are lost.
